Definitions

  • the invention concerns a method for fixing a composite energy-storing flywheel with pre-tension with an inner bore on a coaxial support rotating symmetrically with the latter and having a tapering outer surface, in which a ring is placed in the flywheel bore, said ring having a tapering inner surface, of which the taper corresponds with that of the support and the entire unit thus obtained is shifted on the support until the desired pre-tension is obtained.
  • the ring used in this known method has a cylindrical outer surface, fitting within the cylindrical bore of the flywheel, and is provided with a number of incisions running over the greatest part over its length.
  • a consequence thereof is that the ring is elastically deformable in a radial direction due to changes in the widths of the incisions, with which it is intended to accomplish, that by placing the ring with the tapered inner bore on the tapered rotating symmetrical support, the outer surface in contact with the inner bore of the flywheel deflects outwards, thereby generating radial compressive stress in the flywheel.
  • the aim of this invention is to overcome this objection.
  • this aim is achieved by designing both the inner bore of the flywheel and the co-operating outer surface of the ring, with a corresponding taper.
  • FIG. 1 is a longitudinal section through a flywheel energy storage unit, in which the flywheel parts have been fixed according to the method of the invention
  • FIG. 2 is a partial section on an enlarged scale of an energy-storing flywheel part, in combination with the used clamping ring in accordance with the invention
  • FIG. 3 explains the use of this clamping ring in combination with the flywheel part in a drawing which is not to scale.
  • FIG. 1 schematically shows a flywheel energy storage unit in its entirety indicated by reference numeral 2, containing a housing 4, with in it a stator 8 with stator windings 10, supported by suitable supports 6a and 6b.
  • stator 8 By means of suitable bearings 12a and 12b stator 8 bears a rotor 14, which consists of a rotor bush 16 and the disc-shaped flywheel parts 18a-18d, which are fixed on the rotor bush.
  • a rotor 14 which consists of a rotor bush 16 and the disc-shaped flywheel parts 18a-18d, which are fixed on the rotor bush.
  • Each of these flywheel discs has a wound and therefore stratified structure, as for example known from EP-A- 0 137 759.
  • the outer surface 20 of the preferably steel rotor bush is tapered, in such a way that this surface 20 encloses with line 22, which is parallel to the rotor bush centre line 24, an angle ⁇ , in such a way that the diameter of the outer surface part 20a of rotor bush 16 increases from left to right up to half of the length of the rotor bush, after which the diameter decreases again with the same degree of taper.
  • clamping rings 22a-22d are used between the respective flywheel parts 18a-18d and the outer surface of rotor bush 16 which have a corresponding taper with inner surface 24a, which co-operates with the outer surface of rotor bush 16.
  • this taper has been drawn in an exaggerated way, and it is also indicated by angle ⁇ .
  • the outer surface 26a of clamping ring 22a also has an increasing conical design, indicated in FIG. 3 by angle ⁇ .
  • This taper is also present at inner surface 28a of flywheel part 18a.
  • There the angle between this inner surface and a line parallel to the flywheel centre line is also equal to ⁇ .
  • these angles which in practice are approx. 0.8° degrees if there is a proved suitable degree of taper of approx. 1:80, have been drawn larger in an exaggerated way in FIG. 3.
  • a ring for example ring 22a
  • the matching flywheel part for example flywheel part 18a
  • the flywheel part is pressed on the rotor together with the ring. In this way the correct radial pretension is obtained if the dimensioning is correct.
  • rotor bush 16 consists of two parts, 20a and 20b, with a mutually opposed taper, rotor parts 18b and 18a are applied to the left on the rotor with their clamping rings 22b and 22a, while rotor parts 18c and 18d are applied to the right of the rotor with clamping rings 22c and 22d.
  • clamping rings are not only applied between a flywheel part and the rotor bush, but also between two radially connected sections of a flywheel part designed with a suitable configuration, as indicated in FIG. 1 for flywheel parts 18a' and 18a", with clamping ring 22a', which is marked by broken lines and situated in between. It is also possible to combine the use of a clamping ring in accordance with the invention with the usual thermal contraction. Finally, the clamping ring can be used for fixing balancing weights.
  • the wear of the ring on the axle can be prevented by coating the axle with a thin coating of ceramic material (not indicated in the figures) preceding the application of the ring.
